ARM: dts: stm32: enable USB OTG HS on stm32h743i-eval
This patch enables USB HS on stm32h743i-eval in OTG (DRD) mode. The USB connector used will determine the role of USB OTG controller. Signed-off-by: Amelie Delaunay <amelie.delaunay@st.com> Signed-off-by: Alexandre Torgue <alexandre.torgue@st.com>
